ABS & emergency dash lights will turn on/off intermittenly; no pattern as to when/how often. Had GM dealer check it. My ebcm had a short, if lights were on, had no ABS, just hydraulic if lights were off. I have ABS. Cost of new module is $1100; plus labor!! dealer suggested I live with it for cost of repair! I agreed, but worried that GM probably were ignoring lights & thinking they had good ABS!!

: the contact stated while traveling 35 mph the contact depressed the brake pedal and it went to the floor. As an attempt to stop the vehicle the contact pumped the brakes., resulting contact in a rear end collision. This incident occurred on wet road conditions. The vehicle was towed to an independent towing service.

Shortly after I purchased my 2000 GMC Sonoma [xxx] I had a "low speed activation" of the ABS. Some time later the brake warning light was activated. I took the truck to a GMC dealer and was told I had no problems, but they did replace the brake shoes. Ever since then the low speed activation would happen periodically. Recently, the problem has evolved to every day. And I believe this root problem is behind a lot of other brake problems I've had with this vehicle.

When traveling at highway speeds ABS light comes on, and brake light on dash blinks although brakes are not being applied. Brake light will stop blinking if vehicle is slowed down, but the ABS light will stay on until key is taken from ignition. Dealer has seen vehicle 3-4 times, and can not fix it.

Consumer was traveling 30mph, and upon making a turn onto a street vehicle shut off without prior warning. He lost steering, and threw vehicle in park. Vehicle stopped abruptly. Consumer's head went through the windshield. Driver's side airbag didn't deploy, and driver side seatbelt didn't hold him at all. Second incident occurred traveling about 65mph on highway, and vehicle shut down again. During both incidents ABS braking light appeared on dashboard. Dealership was aware of problem.

Anti-lock system defective in strategy of operations. Seems designed for icy roads and activates under the lightest of braking applications on front wheels with 1-2 second recovery time (without brakes) with only slight pedal & slight wheel bounce. This happens with 1-2 passengers & about 75-100 pounds in truck ped (bed cover) on dry streets approaching intersection with ripples or potholes on one side with very light slow (grandpa style driving) light braking- front wheel senses the slightest lockup & deactivates brakes (1-2 second recovery time) & then reapplies. This has resulted in multiple times of leaving me in intersection with vehicles skidding to stop to keep from T-boning my vehicle. Have complained to dealership management, GM district field rep who tell me this stratedgy is normal. This stratedgy will get people killed if it hasn't already.they told me there is nothing they can do. This report is being made to hopefully force something to be done. I could do better job of preventing brake lock up using ancient mode of stab breaking if necessary but wouldn't need to under descibed scenario.

ABS pulled when two of the tires on vehicle were not on the same type of road surface, causing vehicle to crash, during the accident, the airbags experienced no deployment, the service manager agreed that the ABS was not functioning properly however the computer showed that none of the sensors failed.

Maumee Ohio accident report #004028. Brake failure. Extremely cold weather, ten degrees Fahrenheit. Bumper-to-bumper traffic rolling downhill to a light. Both clutch and brake pedals were depressed with strong, steady foot pressure at 15-20 mph. ABS pulsing activated. Vehicle gradually slowed to 10-15 mph. But, other vehicles came to a complete stop in the same distance. So, a rear-end collision occurred at 10-15 mph. It is reasonable to speculate that the road surface was frozen. But, no ice was observed by either driver or by law enforcement. And all of the other (heavy) traffic stopped without incident. This vehicle also exhibits degradation of braking performance on rough pavement; the ABS kicks in with light brake pedal pressure at 15 mph even on dry pavement, so long as it is somewhat bumpy.

Anti-lock brakes engage and pulsate to slow down but not stop when going over bumps on paved surfaces. Includes all speeds. On one occasion this caused me to proceed an extra estimated 15 feet into an intersection where an accident occurred. Dealership and manufacturer contacted and system checked. Was not satisfied with the inspection of the braking system. Since this incident, this has happened again, although with no resulting consequences.
